A disc recording and/or reproducing apparatus provided with disc exchange function to carry out recording/reproduction while carrying out exchange between plural discs held within a disc holding body. This recording and, or reproducing apparatus comprises a disc holding body within which plural discs are held at predetermined intervals (spacings) in a stacked state, a biasing member for biasing respective discs held within the disc holding body in a direction projected from the disc holding body, a recording/reproduction unit for carrying out recording and/or reproduction of information signals with respect to the optical disc drawn out, and a carrying mechanism for taking out a predetermined one disc from the disc holding body to carry it to the recording/reproduction unit. This carrying mechanism includes a drawing mechanism, and allows this drawing mechanism to move at least the other one disc adjacent to a predetermined one disc held within the disc holding body toward the internal of the disc holding body against biasing force of the biasing member to draw out only the predetermined one disc in a direction projected from the disc holding body, thus to carry it.
